Detection And Modeling Of Radiation Induced Effects In Tissues By Dielectric Spectroscopy, Dorin A. Todor

Physics Theses & Dissertations

The work presented here is applied physics research in the field of radiation treatment. We address the development of a new and innovative method, in vivo and possibly non-invasive, for tumor and healthy tissues control during and after the radiation treatment. The radiation treatment is delivered in an almost standardized manner for particular classes of tumors. The large variance in the individual radio sensitivity of healthy tissues and tumors often leads to local recurrence of neoplastic growth and/or distant metastatic disease which often remains untreated. The method is based on the measurement and analysis of electrical impedance data in …

Virtual Compton Scattering In The Nucleon Resonance Region, Luminita Anca Todor

Physics Theses & Dissertations

This thesis is a study of virtual Compton scattering reaction in which a virtual photon is elastically scattered off a proton γv p → γp. The p( e,e′p)γ reaction was measured in the nucleon resonance region for the first time in the experiment E93-050 in Hall A at Thomas Jefferson National Accelerator Facility. To lowest order in ^αQED, this reaction is a coherent superposition of radiation from the incident or scattered electron in elastic ep scattering (Bethe-Heitler) and exclusive production of a photon on the proton, by absorption of a virtual photon …

Teaching Prayer: Pilot Survey Of Academic Courses On Personal Prayer, E. James Baesler

Communication & Theatre Arts Faculty Publications

The practical concerns of an individual interested in learning about prayer in an academic context are interconnected with the practical concerns about teaching an academic course on prayer. A pilot study proposed to investigate and evaluate the context and content of academic courses on personal prayer from the perspective of teaching prayer, asking what proportion of institutions of higher education offer courses on prayer, in which department, and on what level. The search was limited to the Christian faith, and in particular to private colleges and universities of the Catholic denomination. An online Internet search yielded a sample of 126 …

Doctrinal And Applied Tqm In Relation To Dominant Models Of Organisation: A Comparative Study, Brad J. Moore

Theses : Honours

Total Quality Management (TQM) is examined in five organisations in light of the assumption that its implementation is an ongoing negotiated order rather than an objective reality as often accepted by the literature. Guided by a theoretical framework identified by Spencer (1994) and a qualitative methodology suggested by Miles and Huberman (1994), the perceptions of a cross section of organisational members in five organisations are used to establish the nature of applied TQM in terms of mechanistic and organismic 'mental models' of organisation and the degree to which applied TQM varies from the basic doctrine. It is argued that both …

Consumer Perceptions Of The Internet As A Product And Service Infomation Source, Kevin Nguy

Theses : Honours

The Internet is fast becoming an important product and service information source. Consumers are using the medium for gathering information on products and services. The Internet has unique characteristics, which makes it a powerful medium for communication. However, what is the perception of the product and service information on the Internet? This study aims to contribute to an understanding of consumers' perception of product and service information on the Internet. The research is exploratory in nature. Consumers' perceptions towards the Internet as a product and service information source were measured along a construct relating to perceptions towards the Internet information. …

Vhdl Design And Simulation For Embedded Zerotree Wavelet Quantisation, Hung Huynh

Theses : Honours

This thesis discusses a highly effective still image compression algorithm – The Embedded Zerotree Wavelets coding technique, as it is called. This technique is simple but achieves a remarkable result. The image is wavelet-transformed, symbolically coded and successive quantised, therefore the compression and transmission/storage saving can be achieved by utilising the structure of zerotree. The algorithm was first proposed by Jerome M. Shapiro in 1993, however to minimise the memory usage and speeding up the EZW processor, a Depth First Search method is used to transverse across the image rather than Breadth First Search method as initially discussed in Shapiro's …

Biofilm Composition And Function In Stormwater Constructed Wetland Systems On The Swan Coastal Plain, Western Australia, S. A. Hawkins

Theses : Honours

The ability of natural wetlands to act as effective nutrient sinks and to absorb new nutrient loadings is well documented. Constructed wetland systems (CWSs) aimed at optimising these nutrient removal mechanisms have been used for the removal of nutrients and pollutants from a variety of waters and wastewaters over the past thirty years. Over the past decade, the use of CWSs has extended to the removal of nutrients from urban stormwater, as a more ecologically sensible management option to the traditional method of discharging stormwater into natural wetlands. Stormwater CWSs on the Swan Coastal Plain are designed to remove phosphorus. …

Salinity Tolerance Of Selected Ectomycorrhizal Fungi (Pisolithus Tinctorius Pers.) And Ectomycorrhizal Eucalypts, Ben Bradshaw

Theses : Honours

Increasing soil salinity has become a major problem worldwide. It has led to a reduction in the amount of arable land, has put at risk the supply of freshwater and threatens the existence of many natural habitats. The major increase in salinity has been attributed to human activities such as clearing of natural vegetation and large-scale irrigation programmes. The alleviation of this problem has focussed on changed management strategies. the most significant of which is the re-establishment of deep rooted plants in sail affected areas. This, however, is difficult because of the variation in salt tolerance of such plants and …

Study Of Fermion Pair Production In E+E- Collisions At 130-183 Gev, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

The cross sections and forward-backward asymmetries of hadronic and leptonic events produced in e+e−e+e− collisions at centre-of-mass energies from 130 to 183 GeV are presented. Results for e+e−e+e−, μ+μ−μ+μ−, τ+τ−τ+τ−, qq¯qq¯, bb¯bb¯ and cc¯cc¯ production show no significant deviation from the Standard Model predictions. This enables constraints to be set upon physics beyond the Standard Model such as four-fermion contact interactions, leptoquarks, Z′Z′ bosons and R-parity violating squarks and sneutrinos. Limits on the energy scale ΛΛ of e+e−ff¯e+e−ff¯ contact interactions are typically in the range from 2 to 10 TeV. Limits on R-parity violating sneutrinos reach masses of a few …

How The Grateful Dead Turned Alternative Business And Legal Strategies Into A Great American Success Story, Brian C. Drobnik

Vanderbilt Law Review

That the Grateful Dead were "different" undoubtedly is true on a broad social level. But it is not so easy to ascertain how they were different in the business and legal aspects of their enterprise. The ephemeral nature of their approach stems from the fact that they conducted their affairs within and alongside the world of statutes and contracts and yet provided themselves with a great degree of independence from that world. This Note will comment on the Dead's perspective on and their ultimate rejection of many of the business and legal strategies traditionally ascribed to in the industry. After …

Software Piracy: Attitudes & Opinions Of Computer Users And Implications For Software Manufacturers & Consumers, Bharath Pola

Presidential Scholars Theses (1990 – 2006)

Computer software became registered as a form of literary expression by the United States Copyright Office in 1964. By 1980, the Copyright Act was amended to explicitly include software applications. Today, it is illegal to create copies of original program disks without express permission from the manufacturer (Microsoft 1994). The Software and Information Industry Association (SIIA) states that $2.4 billion worth of copyrighted software was pirated in 1990. This figure represents almost one-half of the total revenue of the software industry for that year. An additional $10 to $12 billion was lost to pirates overseas. However, such statistics maintained by …

An Inquiry Into The Development Of Expert Systems In Legal Reasoning, Trevor K. Sheeley

Presidential Scholars Theses (1990 – 2006)

The first goal of this paper is to review some of the steps necessary in developing a system that reasons effectively in some domain of law. The paper will begin by addressing the issues of domain selection, domain analysis and knowledge acquisition, knowledge representation, and selection of an inference method. After presenting a brief argument against using rule-based reasoning as the primary mode of inference, the paper will go on to expound the virtues of Kevin Ashley's HYPO, a software model of case based legal argument. It will conclude with a short description of my experience implementing part of a …

Structural And Electrical Characterization Of A Novel Mixed Conductor: Ceo2 - Sm2O3 - Zro2 Solid Solution, W. Huang, P. Shuk, M. Greenblatt, M. Croft, Fanglin Chen, M. Liu

Faculty Publications

solid solutions were synthesized for the first time by the hydrothermal method. The electrical properties of the solid solutions have been studied in air and under reducing conditions. Solid solutions with the fluorite structure were formed in all of the studied range of substitution after calcination at 1500°C. With increasing substitution up to 30 mol %, the electronic conductivity increases under a reducing atmosphere. The solid solution has good mixed electronic and ionic conductivity; the total conductivity is 0.42 S/cm at and 700°C with an estimated ionic conductivity of ca. .

Adding A Filter To Your Parts Washer, Jeff England

Iowa Waste Reduction Center Book Gallery

Filtering parts washing solvent is a good way to increase the life of cleaning solvent, and improve the cleaning performance of a parts washer. There are several options when considering filtration. If a business is adding or replacing units, the reasonable thing to do is to simply purchase a parts washer with a filtering unit built in. However, if the cost of new units is a concern, or if the old units are in working order, it might be more desirable to add a filtration unit to the current system.

The Ups Prototype: An Experimental End-User Service Across E-Print Archives, Herbert Van De Sompel, Thomas Krichel, Michael L. Nelson, Patrick Hochstenbach, Victor Lyapunov, Kurt Maly, Mohammad Zubair, Mohamed Kholief, Xiaoming Liu, Heath O'Connell

Computer Science Faculty Publications

A meeting was held in Santa Fe, New Mexico, October 21-22, 1999, to generate discussion and consensus about interoperability of publicly available scholarly information archives. The invitees represented several well known e-print and report archive initiatives, as well as organizations with interests in digital libraries and the transformation of scholarly communication. The central goal of the meeting was to agree on recommendations that would make the creation of end-user services -- such as scientific search engines and linking systems -- for data originating from distributed and dissimilar archives easier. The Universal Preprint Service (UPS) Prototype was developed in preparation for …

An Empirical Analysis Of The Critical Determinants Affecting Commitment And Performance Of The U. S. Firm In The South African Market: Apartheid Versus Post-Apartheid, Sonja Pollard Mitchell

Theses and Dissertations in Business Administration

Recognized by the U.S. Chamber of Commerce as one of the world's Big Emerging Markets (BEMs), South Africa has received vast attention from potential foreign investors (IRRC 1994) and has been recognized by scholars as an excellent base for research (Hofmeyr, Templer and Beaty 1994). Unfortunately, little is known about the export behavior of the foreign firm in South Africa (Calof and Viviers 1995) given the country's history of political, social and economic instability.

This dissertation is an effort to increase the understanding of the factors that contribute to the commitment and overall market performance of U.S. firms in South …

The Inherent Limits Of Judicial Control Of Agency Discretion: The D.C. Circuit And The Nondelegation Doctrine, Richard J. Pierce Jr

GW Law Faculty Publications & Other Works

The article discusses American Trucking Associations v EPA, in which a two-judge majority of a DC Circuit panel held that the section of the Clean Air Act that authorizes EPA to set primary air quality standards applicable to criteria pollutants is unconstitutional as interpreted by EPA. The court held the EPA interpretation unconstitutional because it provides no criteria for determining how much pollution is too much. The court remanded to allow EPA the opportunity to adopt a saving interpretation of the statute by adopting a binding determinate decision making standard that EPA and a court can apply to determine how …

Family Leave And The Gender Wage Gap, Michael Selmi

GW Law Faculty Publications & Other Works

In this article, I argue that the key to achieving greater gender equality in the workplace is finding a way to change the behavior of men with respect to the care of children. Until now, most suggestions have focused on changing the behavior of women or employers, but women continue to face significant disadvantages in the workplace despite substantial changes in their labor force behavior. In the first part of the article, I analyze the latest data and conclude that the gender pay gap reflects both women's actual labor market behavior, which still differs from men's, and employers' exaggerated responses …

Adaptive Object-Oriented Filtering Framework For Event Management Applications, Ehab Al-Shaer, Mohamed Fayad, Hussein Abdel-Wahab, Kurt Maly

Computer Science Faculty Publications

Event filtering is an essential element in event management applications. In event management environments, the filtering mechanisms are employed to track the events generated from applications at run-time and perform the corresponding appropriate actions. Several key applications domains, such as system and network management, distributed system toolkits, communication protocols and active databases, utilize event filtering for various management purposes. The goal of this paper is to describe the object-oriented design and implementation of an adaptive event filtering framework which can be integrated and reused efficiently to develop event management applications for various domain environments. In our approach, the event filtering …

Losing Ground : Locational Formulations In Argumentation Over New Travellers, Rebecca Barnes

School of Psychology Theses

This thesis is an exercise in discursive psychology. The body of discourse analysed concerns the defence of rural space against New Travellers. In contrast to previous sociological and human geographical work in this area, instead of newspaper articles and Parliamentary discourse, participants' talk and texts are the starting point for the - investigation. The data corpora have been generated from a variety of sources: Focus group discussions with police officers; interviews with landowners (or their representatives); letters to the editors of local newspapers; and private letters of complaint to a local council. The thesis focuses on the participants' selection of …
